Marginalization like a projection

Juan Francisco Verdegay López, Serafín Moral Callejón


This paper studies the problem of marginalizing convex polytopes of probabilities
represented by a set of constraints. This marginalization is obtained as a special
case of projection on a specific subspace. An algorithm that projects a convex
polytope on any subspace has been built and the expression of the subspace, where the
projection must be made for obtaining the marginalization, has been calculated.
